Application liled'lq'ovember 17, 1911. Serial No. 660,820.

Be it known that 'I, 1 Griimhns Dwloirr AVERY, a citizen of theUnitedStates, IGSldand State of Wyoming, have invented new and usefulImprovements in Sanitary Drinkin'g-'Fountains, of which the following isa; specification.

My invention reiates'to improvements in: sanitary drinking fountainsforuse espe cially in railway coaches, oflices" and other; public placeswhere'a continual flow of water is not available. g

The object of my improvements is to pro-= constructed fountain withremovable parts capable of being easily cleansed, at the samei timeornamental, and one whereby the drinking water may be conserved. Iattain these objects by the construction illustratedin the accompanyingdrawings, in whioh- &

Figure 1 is a plan view of the-fountain and water supply connections.Fig. 2--is'a A-B, Fig. 1. Fig. 3-is a detail plan. View of the innercone. Fig. 4:,is-a detail plan view of the outer cone. Fig. 5 is adetail view of the inner cone, the right half being in side elevation;and the left half being in section on the central vertical plane. Fig. 6is a corresponding detail view of the outer cone. Fig. 7 is acorresponding de tail view of the guard ring and supports. Fig. 8 is adetail plan view of the guard ring and supports. The same numerals referto similar parts throughout the several yiews.

Number 1 is a water tank, watermain or any suitable source of supplyof-drinking water, to which is connected the drinking fountain by meansof feed pipe 'At any convenient place in feed pipe 2 is located a waterto the drinking fountain. Pipe 2 is supported by the water tank, or byany suit-. able means, and the fountain end of the pipe is curved insuch manner that when in place it stands in a vertical position tosupport the drinking fountain, and is threaded at 4 to allow the innercone 6, threaded to correspond, to be screwed on and supported by pipe2; 5 is any suitable regulating valve in pipe 2 to regulate the How andfountain of water. I

6 is a hollow pipe like inner cone threaded threaded outlet 10 intowhich screwed a drain pipe 11.

inside at its base-to screw on pipe 2, and

openat its apex at 21 forming an inner *water chamber 19. Inner cone 6has a horiouter water chamber 22. Vertical flange 8 is threaded at 9 topermit the outer.or fountain cone 12, threaded to correspond, to bescrewed into place over the rim ofth'e cuplike chamber of the innercone. The base flange 7 of the inner cone is provided with a i may beOuter or fountain cone 12 has a rolling flange-13- at its base with areverse flange 14 thereon threaded inside to screw on the innerconethreads 9 on. the cup rim; this "outer cone 12' is provided at itsbase with any suitable number of drains 15, and is hollow and open atits apex forming a water vent or fountain nozzle 20. When screwed intoplace the open apex "21 of the inner cone fits tightly up against theinside of the apex of the outer cone and water chamber central verticalsection on the plane of-i'inei A guard ring16 is supported symmetricallyabove the two cones by supports 17 screwed orriveted to the flange 13 ofthe outer cone by screws. or rivets 18. The guard ring is supportedabove the apex of the fountain cone so that a person drinking will restagainst the ring and his lips will not touch any part of the fountain.

In operation the spring push valve is pushed allowing Waterto passthrough pipe 2, with its regulating valve 5 set to allow the roper forceof water at the fountain nozziia 20, through the inner water chamber 19of the inner cone up through the water vent 20 at the apex of the outercone forming a fountain above the outer cone and inside the guard ringand spilling over the entire outer surface of the outer cone 12. Thewaste water caught by the rolling flange 13 passes through drains 15into the outer chamber 22 formed by the flanges on the base of the innercone and thence through the outlet 10 into drain pipe 11 where it iscarried to a sewer or any suitable place.

The person drinking places his mouth in: a

cone being prevented by the guard ring. The flow of water at the time ofdrinking washes off the entire outer surface of the outer cone. aterconservation is effected since there will be no tendency to cause thewater to run while theperson is not drinking.

The entire fountain or parts may be made of any suitable material, asmetal, glass or porcelain, and if made of metal all exposed parts may benickel plated to prevent rust and corrosion.

I claim 1. The combination in a drinking fountain of an inner hollowcone open at its apex andbase having a cup-like outer chamber formed byflanges at the base of said inner cone, an outer cone open -at its apexhaving a rolling flange at its base adapted to fit over the outerchamber of the inner cone, and the open apex of the outer cone adaptedto fit upon the apex of the inner cone with a guard ring supportedadjacent an above the apex of the outer cone.

2. The combination in a drinking fountain of the hollow outer cone openat its apex having a rolling flange at its base with a re verse flangeon said rolling flange, an inner hollow cone having an open apex adaptedto fit against the inner side of the open apex of the outer cone, saidinner cone having flanges at its base adapted to support the outer conewith means consisting of water connections to deliver water inside theinner cone.

3. The combination of an inner conehaving an inner pipe-like chamberopen at its apex and threaded at its base and having an outside diskflange on its base, said disk flange being flanged vertically forming acup-like outer chamber, an outlet in the base of said cup-like outerchamber, an outer cone supported above said inner cone having an openapex in juxtaposition with the open apex of the inner cone, said outercone having a rolling flange at its base with drains to the outerchamber of the inner cone, a guard ring supported upon the flange of theouter cone above and adjacent to the open apex of the outer cone,substantially as described.

4:. The combination in a drinking fountain of a hollow inner cone openat its apex and adapted to screw on a pipe at its base, said inner conebeing flanged at its base forming a cup-like outer chamber, an outerfountain cone open at its apex adapted to fit over the inner cone withits open apex in juxtaposit-ion with the open apex of the inner cone,said outer cone having a rolling flange at its base perforated to formoutlets, said rolling flange having a reverse flange adapted to screwupon the rim of the cup-like outer chamber of the inner cone, a guardring supported above and adjacent to the open apex of the outer cone tsupports attached to the flange of the outer cone substantially asdescribed.

5. In a drinking fountain a water pipe with a control valve therein,said pipe supporting an inner conehaving an inner chamber connected withsaid pipe and an outer chamber formed by flanges at the base of saidinner cone, said inner chamber having an opening at the apex of the coneand said outer chamber having an outlet, an outer cone supportedabove-said inner cone having an open apex coinciding with the open apexof the inner cone, said outer cone having a flange at its base withdrains into the outer chamber of the inner cone with a guard ring heldby supports attached to said outer cone above and symmetrical with theopen apex of the outer cone, substantially as described.
